HYGIENIC SIPI-ION.

To all whom it may concern:

Be it known that I, ALBERT J. AoKnnMAN, a citizen of the United States,and resident of New York, county of New York, State of New York, haveinvented certain new and useful Improvements in- Hygienic Siphons, ofwhich the following is a specification.

The present invention has for its object an improvement in siphons forbottles or the like whereby the same is made thoroughly hygienic and themeans by which I produce this result reside particularly in adequatedevices for preventing the leakage between the interior of the bottle orother vessel and the external air and also in the character of thematerial forming the siphon head itself.

In carrying out my invention 1 usually make the siphon head of porcelainalthough it may be made of glass or other non-corrod-ible substance andso far as the virtues of the mechanical features of my invention areconcerned they might also be applied to metallic siphon heads.

One feature of my improvements resides in the special means for sealingthe top of the bottle or other vessel which I accomplish by means of arubber gasket having a disk portion lying on the top of the bottle, aplug portion entering the mouth of the vessel and fitting therein, and ascrew-threaded portion on the opposite side of the disk adapted tocooperate with a screw thread in the interior of the siphon head.

Another novel feature of my invention consists of a special constructionof valve and valve-seat commanding the passage way between the exit fromthe siphon head and the usual tube extending into the bottle.

Still another feature of novelty isthat whereby the push button at thetop of the head is prevented from rotary displacement during theoperation of the siphon and at other times.

My invention will be understood by reference to the accompanyingdrawings in which- Figure 1 is a vertical central section through myimproved siphon head and a portion of the top of a bottle to which it isapplied, the main valve being closed; Fig. 2 is a similar section takenat right angles to the view shown in Fig. 1, the main valve be ing open;Fig. 3 is a transverse section along the line B--B in Fig. 1; Fig. 4 isa detail View showing the connection between the Specification ofLetters'Patent.

tube in the bottle and the gasket adapted to close the month thereof;Fig. 5 is an elevation of the push or press button; Fig. 6 is a verticalsection of said button taken along the line C C in Fig. 5; Fig. 7 is anelevation of the valve rod showing a portion of the valve in section;Fig. 8 is a vertical section of the rubber gasket already mentioned, thesection being taken along the line DD in Fig. 9; and Fig. 9 is a plan ofthe gasket.

In the drawings, 1 represents a bottle to which the siphon head, 2, isapplied. Inclosing the neck, 8, of the bottle is a screwthreaded ring,at, presenting no novel features and being the usual means of connectionat this point. The siphon head 2 is provided internally at its lower endwith a screw-thread adapted to engage with a screw-thread 5 adapted toengage with the screw-thread on the ring -l and thereby 'make connectionbetween the siphon head and the bottle.

The features thus far described are not essentially different from thosewhich are ordinarily used in connecting a siphon head and the bottle orvessel to which it is applied.

The novelty of the present invention begins with the means for closinghermetically the mouth of the bottle 1. Broadly, these means consist ofa gasket, 6, pierced at its center by a perforation adapted to receivethe usual tube, 7, which extends down into the bottle and forms aportion of the passage way for the liquid in the bottle on its way tothe exit, 8-, in the siphon head. The opening in the gasket 6 is madesuch that the tube 7 fits nicely into it and thus a good connection isformed between the tube and the gasket, which is made air-tight whenpressure is applied to the gasket as will presently be described. Thegasket is preferably formed in the shape of a disk or plate having adownward extension, 9, forming a plug which enters the mouth of thebottle 1 and is so shaped as to fit closely therein. On the upper sideof the disk or plate is a screwthreaded portion, 10, adapted to engagewith an internal screw-thread in the interior of the siphon head 2.

It will be seen that when the siphon head is screwed down, an engagementtakes place not only between the ring 4 and the screw thread 5, but alsobetween the screw-threaded portion 10 and the interior screw-thread lastdescribed, the pitch of the threads being necessarily such that bothoperations can be performed without injury to the apparatus.

The parts are so proportioned that before the outer screw-thread reachesthe limit of its motion along the ring 4: there shall be a suificientamount of pressure exerted upon the gasket 6 and the parts connectedtherewith to press the same firmly upon the top of the bottle and alsoto exert a slight compression toward the center whereby the tube 7 ismade to have an air-tight connection with the gasket.

The passage above the top of the tube 7 inside the siphon head 2 isprovided with a valve seat, 11, adapted to receive a valve, 12, mountedon the lower end of a valve rod or stem, 13. The said valve rod isprovided with a screw-thread at its upper end and adapted to be screwedinto the cap of the ress button 14:, as shown in Figs. 1 and 2.

The stem 13 is made of hard rubber and is provided at its lower end withan enlargement, 15, generally pear shaped, such enlargement beingsurrounded by a soft rubber part, 12, which constitutes the valveproper. The enlargement 15 may be secured to the main stem 13 by screwconnection. At the bottom of the enlargement 15 is a slot, 16, for theinsertion of a screw driver whereby the stem may be screwed into placein the cap 14.

The enlargement 15 is provided with slots, one of which is shown at 17and the soft rubber piece 12 is provided with lugs on the inside whichenter the said slots and hold the soft rubber piece in place.

It will be seen that owing to the shape of the conical piece 15 and thedimensions of the opening in the bottom of the soft rubber piece 12, itis quite possible to slip the said soft rubber piece into place afterthe part 15 has been joined to the stem 13 or even in case the two lastnamed parts are made in one piece. Thus, the soft rubber piece may bemade to assume its proper position with the lugs entering the slots 17,without the necessity of molding the rubber piece upon the conicalenlargement 15.

The stem 13 passes up through a small opening in the siphon head abovewhich it is surrounded by a spiral spring, 18, pressing surrounding thestem 13. The spring serves to hold the press button out in the positionshown in Fig. 1 except when the same is pressed down in order to pushthe valve 12 away from its seat.

The cap 1a is provided with a hollow shank, 21, within which the spring18 opcrates and this shank is cut away along half its length so as toform a shoulder corresponding to an internal shoulder 22, near the topof the siphon head. The shoulder 22 occupies practically as much spaceas is cut away from the shank 21, from which it results that the shankand button when properly put in position are held from rotation, thoughfree to reciprocate vertically. These means of preventing the rotationof the press button are simple and effective and form one of theimportant features of my invention.

A suitable material for the gasket 6 is soft rubber, although othercompressible materials may be used.

I am aware that means for preventing a rotary movement of the button andits shank are known in the art, but I am not aware that the particularmeans described herein are familiar, and I believe them to be novel,
